One、 Differences between high-frequency and low-frequency locks in hotels
1、Different operating frequencies
Low-frequency card: The low-frequency card operates at a frequency range of 30kHz - 300kHz. Typical operating frequencies include: 125KHz, 133KHz.
High-frequency card: The operating frequency range of high-frequency cards is 300MHz-300GHz. Typical operating frequencies include: 325KHz, 533KHz.
2、Different types of cartridge
Low-Frequency Card: A low-frequency card is an active card, requiring the card to be actively brought close to the reader. The user must place the card within the card reading area of the reader to read the information on the card and complete the transaction.
High-frequency card: A high-frequency card is a passive card that does not require the presentation of a card. Simply passing the card through a reader can read the information on the card and complete the transaction.
3、Different advantages
Low-frequency card: Low-frequency card chips typically use standard CMOS processes, characterized by energy efficiency and low cost. Their operating frequency is not subject to radio frequency regulations.
High-frequency card: High-frequency cards store a large amount of data and have a relatively small number of antenna turns. They are suitable for high-speed, long-distance identification applications.
Two. What type of card is used for hotel locks?
1、Project debugging card
- Commonly used for installing and testing hotel door locks, enabling the opening of installed hotel door locks, including those in a locked state, while also placing the lock in a normal open state.
2、 Total card
Master cards are typically held by hotel management personnel and can be used to unlock all doors, including those that are already locked.
3、Guest cards
- Can be used for guests to access designated rooms, but cannot unlock doors in a locked state.
4、Emergency card
This device, operated by hotel managers or security personnel, can be used in emergency situations such as fires. It can unlock all doors, including those that are already locked, and maintain the doors in an unlocked state. When the emergency card is used again, the door lock will return to its normal state.
5、Area Cleaning Card
The system allows unlocking of doors in designated areas, but not doors that are already locked. Users can set up three active time periods and five different areas for door unlocking.
